I couldn't find these bulbs in the local big stores. This is a 7w bulb that is the same size, shape, color temperature and lumen output as the bulbs that came with my window candles. The quality seems very similar to the bulbs they replace, so I'm not expecting much in terms of durability. Every time a window candle is knocked off the windowsill, it goes into super bright mode and burns out within a day. A stronger thread increases it to 5 stars.
